15- COLORED SOFT CONTACT LENS Abstract of the Disclosure A cosmetic contact lens is lathe cut from a body of stacked discs fused together. The discs are made from hydrophilic polymer, some of which are colored (pigmented or dyed). The pupillary area is formed in a central zone of the lens from a clear layer. The secondary zone formed about the central zone is formed at least partly from one or more colored layers. The peripheral zone formed about the secondary zone is formed from a clear layer. All of the layers are disposed generally parallel to the circular edge of the lens, and the layers may be flat or they may be segments of spheres. This construction provides concen- tric rings of colors in blended, overlapping relationship for covering the iris and giving a cosmetic effect.
